With the easy-to-use interface, you can centrally manage all of the virtual machines created on the TS-251 with minimal effort.

With these permissions, users can work independently on their VM without worrying about their work being interrupted or data being lost because another user has accidentally powered-off the VM. User-based permissions include: Console permissions: Control and View-only/ VM controls: Power, Snapshot and Advanced.

Real-Time & Offline HD Video Transcoding

The TS-251 delivers superior real-time Full HD video transcoding to convert your videos to formats that can be smoothly played on PCs, mobile devices and Smart TVs. It allows for up to 5 devices to simultaneously view different videos stored on the TS-251 with on-the-fly hardware accelerated transcoding. The TS-251 allows you to enjoy instant videos on multiple devices - even those that lack computing power or have limited file format support - without the need for complicated and time-consuming file conversion. With the benefit of offline transcoding, if you can only connect to an Internet connection with limited/restricted bandwidth, you can still enjoy smooth videos by selecting a pre-rendered lower resolution to play the videos via File Station, Video Station, or the Qfile app for iOS & Android without affecting the TS-251’s performance running other applications. This also allows more people to play videos via streaming. The TS-251 also allows you to set a dedicated folder for automatic video transcoding.
